Is it Working?

Course is very successful

Teach it every quarter: senior Ugradsand 1st yr Grads

Have to cap the class size due toresource limitations (equipment and labassistants)

In order to configure the new network topology, we need tochange the current IP addresses of each PC interface card. Thenew IP addresses that we want to use are as shown in thefigure. (Note that 52.100 is an abbreviation for 154.81.52.100.This notation applies to all the PC and router addresses givenin the figure above.)

Exercises:

Change

the

IP

addresses

of

the

PCs

to

reflect

the

network

configuration

as

shown

in

the

figure.

Also

configure

the

routers.

Save

the

output

of

netstat

-rn

or

route

–ee

before

building

the

PCs’

routing

tables.

After

examining

the

figure,

build

the

static

routing

tables

in

all

the

PCs

manually.

Use

netstat

–rn

or

route

–ee

to

verify

your

entries.

Use theping

andtraceroute

programs to test theconnections. Save thetraceroute

outputs

Questions and Report

What is the subnet mask for this subnettednetwork?

For each IP address that you assigned, identify thesubnet ID and the host ID.
